[wellylug] OpenLDAP - aka slapd

[Cliff Pratt]

Hi Glen,

I accidentally deleted this and had to resurrect it...8-(

Anyway.

I'm not sure now that it is a corruption. When we run 
db_recover on it, it fixes the problem. The problem being 
that LDAP stops responding and slapcat hangs. The DBA 
suggested that it might be a dead-lock problem so the next 
time it happens we will try db_deadlock first.

The man page for db_deadlock implies that it can be run 
safely at any time, and that it should preferably be run as 
a daemon. Do you do that?

I'm sticking with debian packages, but I've got a number of 
versions of OpenLDAP and bdb around. Not good, I know. I'll 
have to check the mix. How do you determine which version of 
bdb you have, by the way?

I'm setting up replication from the live master to a slave. 
I'll then take down the slave to do backups - taking down 
the master brings all sorts of problems with the 
applications, due, I think to them losing connectivity with 
the master.

Cheers,

Cliff
